Oil Movement Management System

An oil movement system (OMS) manages all pipelines, crude oil and product storage tanks in the tank farm area and controls the movement of all intermediate components and finished products. It is also known as the Off-site Area Management Application and closes the loop between basic control systems and IT systems. OMS provides a collaborative environment for the offsite operations and provides an overview of all important events, tasks, data, instructions and activities within this area.


The major objectives of OMS are:

  • To scan and record all relevant raw process data (mainly automatically measured levels, temperatures and selected flow rates) in a long-term data historian.
  • Process this data to derive additional parameters and record them similarly (e.g. derivation of volumetric flow from levels, derivation of mass flow from volumetric flow and density; aggregation of raw data over time to obtain stable values, calculation of rates of change, etc).
  • Tank inventory management.
  • Provide methods of defining oil movements in terms of source, destination, route, quantity, material, etc.
  • Provide real-time live displays showing the progress of movements, including the tank-ranking table (tabulates key information about each tank involved in a movement, showing time to finish, current dip, end dip, movement ID, flow rate, volume remaining, dip remaining, etc.).
  • Provide an alarm acknowledgement system (directed to a dedicated window) for alarms based on tanks, movements and events.
  • Calculate tank compositions and other quality parameters based on movements, estimations, in-line measurements and lab data.
  • Calculate and report on the stocks and net flows in and around the refinery, so as to provide information on what quantities of what materials are stored, and where they are stored, at any time. This logic is to include data on material contained in pipelines, as well as in tanks, but will exclude that held in process units
  • Provide reports on current and historical OMS data of all types. The reports to be produced on demand, on event or scheduled, both as built-in preformatted formats and as user-definable formats via linked external applications.
  • Provide links to external data feeding and receiving systems.
  • Log system and operator activity, including interaction with external systems.

Oil Movement Management provides benefits to refinery off site area Operations staff in the following ways:

  • Provides visibility of all activities and data at the off site area.
  • Improves the Off site area operation integrity through real time monitoring.
  • Improves efficiency of the shipping and marine operations.
  • Support order management at Off sites
  • Stores history of all the data, instructions, actions and movements.
  • Automates data exchange with other systems such as production accounting, ERP, scheduling and others to improve data accuracy and reduce manual data entries.
  • Provide consistent and accurate data to improve planning and scheduling.
  • Provides alerts and escalation capability as needed.
  • Provide a hub for exchange of data with external parties, as needed and allowed by company policy, so exchange of data, reports, requests and acknowledgement can be automated.
  • Provide an important execution and monitoring link between P&S and MES layer
